Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31434, here are decompositions:
- 37 + 31397 = 31434
- 41 + 31393 = 31434
- 43 + 31391 = 31434
- 47 + 31387 = 31434
- 97 + 31337 = 31434
- 101 + 31333 = 31434
- 107 + 31327 = 31434
- 113 + 31321 = 31434
Showing the first eight; more decompositions exist.
